What is the best way to get alert on availability of drop box appointment in India

Hi.

Can some one please let me know what is the best way to get alert on availability of drop box appointment in India

Thanks

There is no official way of getting alerts. You just have to keep checking yourself.

Do I have to fill a new DS 160 if I haven’t been able to obtain a drop Box appointment in last 4 months? Does it have an expiration date after submission?
